Okay Dean,
Lets examine the proposition.
Quote:irrationality is no hindrance to something being 'true'
This is
correct if we define "truth" as "what works"...a position I myself advocate. From my position the "irrationality" merely indicates the ephemeral nature of "truth". In other words, "what works" operationally is subject to intellectual paradigm shifts (Kuhn) which delimit the
bases for expectancy of operational prediction. Such "bases" are what mainstream epistemology tends to be concerned with.
This position of course questions the ontological status of "truth" which is problematic to naive realists and theists. The significance of QM in its handling of the wave-partcle "paradox" in that it underscores the nondualistic nature of "observer" and "observed". From an
esoteric point of view this nonduality is a
generalized principle involved in the concept of "illusion" (NOT "nonsense") but from the point of view of "systems theory" this is resolved by a "levels analysis" desciption by second order cybernetics Von Foerster) as "observation of observation". Piaget is significant in providing the background for such a
alternative "constructivist epistemology" NOT because his concept of "equilibration" was based on "
logical paradox" but because it was based in "systemic conflict" at the level of
biological substrate (a point misunderstood by you in your 1992 thesis). The
biological substratum for "cognition" was taken up and advanced by Maturana with the help of evidence from Prigogines work on autopoietic systems which model "life processes". (A reading of Capra explains the relationship).
Thus the "paradigm shifts" associated with "scientific progress" can be seen as an example of Piagetian equilibration at the level of "social structure". And since "language" constitutes the "blood cells" of such a structure it cannot be "understood" outwith its social function.
